These 10 x 13 inch blue inter-department envelopes are built for repeated internal mail routing. The string-and-button closure supports multiple open-and-reseal cycles without degrading, making each envelope suitable for ongoing reuse rather than single-trip delivery.

The printed routing grid — five labeled columns covering Date, Deliver To, Department, Sent By, and Department — accommodates up to 31 individual entries per envelope. This supports traceable document circulation in corporate offices, healthcare facilities, distribution centers, and multi-site manufacturing operations without requiring separate tracking labels or forms. The blue color enables quick visual sorting when used alongside other envelope colors in a tiered mail classification system.

Each case contains 100 envelopes. The envelopes are parcel-friendly, supporting routine replenishment orders without special handling requirements.
